MANUAL ROAD TEST
This test checks the gears being used in L, 2 or D range when driven
with unoperated gear shift control system.
Test drive vehicle on a level road.
1) With selector lever in P range, start engine and warm it up.
2) After warming up engine, disconnect coupler of solenoid valve
wire as shown in left figure.
3) With selector lever in L range, start vehicle and accelerate to
30 km/h (19 mile/h). Check in this state that 1st gear is being
used.
4) At 30 km/h (19 mile/h), shift selector lever to 2 range and accel-
erate to 60 km/h (37 mile/h).
Check in this state that 2nd gear is being used.
5) At 60 km/h (37 mile/h), shift selector lever to D range and check
that 3rd gear is used when speed is higher than 60 km/h
(37 mile/h).
6) After above checks, stop vehicle then engine, and connect sole-
